ACTA1-Related Adult-Onset Scapuloperoneal Myopathy With Cores and Rods. [PDF]
We report a patient with an adult‐onset, slowly progressive, ACTA1‐related scapuloperoneal myopathy with cores and rods, determined by the heterozygous variant NM_001100.4:c.1001C > T, p.(Pro334Leu). The scapuloperoneal phenotype could represent a distinct subcategory, and the characterisation of this patient with a less severe, different clinical ...

Concurrent Sporadic Late-Onset Nemaline Myopathy and an Excessive Glycogen Accumulation Associated With Monoclonal Gammopathy. [PDF]
ABSTRACT Background Monoclonal gammopathy‐associated myopathies (MGAMs) include light chain (AL) amyloid myopathy, sporadic late‐onset nemaline myopathy (SLONM), and vacuolar myopathy with monoclonal gammopathy and stiffness (VAMMGAS). These subtypes usually occur separately, although rare overlap has been described. We report a patient with monoclonal

Incidence and Prevalence of Congenital Myopathies - A Population-Based Study From Western Sweden. [PDF]
Objective Congenital myopathies are a group of rare genetic muscle disorders. Previous studies have estimated point prevalences which only include surviving individuals. Our aim was to perform an epidemiological study with strict inclusion criteria, using modern diagnostic technology to present both incidences and prevalences, and to describe the ...

Phenotypes of Myopathy-related Actin Mutants in differentiated C2C12 Myotubes [PDF]
Background About 20 % of nemaline myopathies are thus far related to skeletal muscle alpha-actin. Seven actin mutants located in different parts of the actin molecule and linked to different forms of the disease were selected and expressed as EGFP-tagged

OXPHOS complex deficiency in congenital myopathy: A systematic review. [PDF]
This systematic review assessed oxidative phosphorylation (OXPHOS) complex dysfunction in genetically confirmed congenital myopathies (CM). Among 5841 studies screened, 23 publications, comprising 45 CM cases, met the inclusion criteria. OXPHOS dysfunction was identified in 78% of cases, particularly where enzymology was performed, with RYR1 most ...

Shoulder Rotation Test: A New Test for Discriminating Between Functional and Structural Weakness. [PDF]
We introduce the shoulder rotation test, a simple bedside test combining the MRC scoring of shoulder internal rotation (IR) and external rotation (ER), for discriminating between functional weakness (FW) and structural weakness (SW) of the upper limbs.

Monoclonal gammopathy of undetermined significance with associated necrotizing myopathy: a case report and review of the literature [PDF]
Background: Monoclonal gammopathies encompass many types of plasma cell proliferative disorders ranging from benign to malignant. Monoclonal gammopathies that meet diagnostic criteria for monoclonal gammopathies of undetermined significance (MGUS) but ...

Genetic and Structural Variations in Czech Patients With Congenital Myopathies. [PDF]
We present 79 unrelated patients with genetically confirmed congenital myopathy (CM). A total of 113 mutant alleles carrying 97 different variants with a presumed pathogenic effect were identified. All but five variants were small scale. The mode of inheritance was autosomal dominant (AD) (44.3%), autosomal recessive (AR) (43.0%), and X‐linked (XL) (12.
